=head1 Name
App::Sqitch::Config - Sqitch configuration management
=head1 Synopsis
  my $config = App::Sqitch::Config->new;
  say scalar $config->dump;
=head1 Description
This class provides the interface to Sqitch configuration. It inherits from
L<Config::GitLike>, and therefore provides the complete interface of that
module.
=head1 Interface
=head2 Instance Methods
=head3 C<confname>
Returns the configuration file base name, which is F<sqitch.conf>.
=head3 C<system_dir>
Returns the path to the system configuration directory, which is
F<$(prefix)/etc/sqitch/templates>. Call C<sqitch --etc-path> to find out
where, exactly (e.g., C<$(sqitch --etc-path)/sqitch.plan>).
=head3 C<user_dir>
Returns the path to the user configuration directory, which is F<~/.sqitch/>.
=head3 C<system_file>
Returns the path to the system configuration file. The value returned will be
the contents of the C<$SQITCH_SYSTEM_CONFIG> environment variable, if it's
defined, or else F<$(prefix)/etc/sqitch/templates>. Call C<sqitch --etc-path>
to find out where, exactly (e.g., C<$(sqitch --etc-path)/sqitch.plan>).
=head3 C<global_file>
An alias for C<system_file()> for use by the parent class.
=head3 C<user_file>
Returns the path to the user configuration file. The value returned will be
the contents of the C<$SQITCH_USER_CONFIG> environment variable, if it's
defined, or else C<~/.sqitch/sqitch.conf>.
=head3 C<local_file>
Returns the path to the local configuration file, which is just
F<./sqitch.conf>, unless C<$SQITCH_CONFIG> is set, in which case its value
will be returned.
=head3 C<dir_file>
An alias for C<local_file()> for use by the parent class.
=head3 C<initialized>
  say 'Project not initialized' unless $config->initialized;
Returns true if the project configuration file was found, and false if it was
not. Useful for detecting when a command has been run from a directory with no
Sqitch configuration.
=head3 C<get_section>
  my $core = $config->get_section(section => 'core');
  my $pg   = $config->get_section(section => 'engine.pg');
Returns a hash reference containing only the keys within the specified
section or subsection.
=head3 C<add_comment>
Adds a comment to the configuration file.
=head3 C<initial_key>
  my $key = $config->initial_key($data_key);
Given the lowercase key from the loaded data, this method returns it in its
original case. This is like C<original_key>, only in the case where there are
multiple keys (for multivalue keys), only the first key is returned.
